Definitions

  • This invention relates to ski boot bindings, and in particular to a binding for the heel of a touring ski boot.
  • Ski touring or cross-country skiing, involves travelling on snow using very light weight, narrow skis. Suitable terrain for this type of skiing is less steep than most alpine, or downhill ski courses, and involves climbing, walking on level terrain and, inevitably, skiing down moderate slopes. Skis used for touring are long, narrow and of very light construction usually of either laminated wood or fiberglass. Touring boots are lightweight and low cut and have a very flexible sole to allow the boot heel to be raised freely while walking or gliding on the skis. Conventional touring ski boot bindings (of which there are several well known types) attach only the toe of the boot to the ski to allow this.
  • Touring or cross-country ski boots and ski bindings are markedly different from alpine or downhill ski boots and ski bindings.
  • touring ski boots are comfortable and light-weight with soft flexible uppers and flexible soles that are normally attached to the ski at the toe end only.
  • Alpine ski boots are heavy rigid affairs with thick inflexible soles that are attached to the skis at both front and rear ends.
  • Touring ski bindings normally secure the toe only of the ski boot to the ski, and these toe bindings do not have a safety release feature and must be released by hand.
  • Alpine ski bindings have built-in safety release features which automatically release the ski boot in the event of an accident while skiing.
  • Touring ski boot toe bindings serve their intended purpose very well in that they permit the skier to move on his skis with a natural walking motion uphill, on the level and down small slopes.
  • these touring ski bindings do not provide adequate control of the skis when sliding down hill on steeper slopes. That is to say, due to the softness of the touring boot and the flexibility of the sole, the heel of the boot has very little lateral stability when the skier is standing on the ski and sliding downhill.
  • the ski boot should somehow be immobilized and/or attached to the ski at the heel.
  • One known procedure for improving the lateral stability of the heel of the boot on the ski involves attaching a plate with raised, serrated edges to the ski under the heel of the boot to hold the latter in place when the heel is weighted.
  • serrated heel plates do not provide a positive anchoring of the boot heel, and excessive lateral heel movement makes turning the touring ski difficult.
  • Another known procedure involves the use of a cable that extends around the heel of the boot to either the toe binding or to a lever positioned on the ski in front of the toe binding.
  • the cable bindings used on touring skis are designed primarily to maintain the boot in the toe binding while allowing the heel to be raised freely.
  • the vertical hold down of the boot heel may be of the positive type (that is, non-releasable except intentionally by the skier), or it may be of the safety release type that releases automatically when heel stresses on the binding exceed a predetermined value (as when a ski tip goes under the snow or the skier accidently falls).
  • a touring ski heel binding should allow unobstructed vertical motion of the heel.
  • the touring ski boot heel binding of the invention comprises, in its broadest aspect, a frame adapted to be secured to the upper surface of a touring ski, a rotatable heel latch pivotally mounted on the frame for rotating forwardly to its forwardmost position at which position it is adapted to engage the heel of a touring ski boot and also for rotation rearwardly to its rearwardmost position at which position it is out of engagement with the heel of the ski boot, and latch engagement and disengagement means for maintaining the heel latch in engagement with the heel of the ski boot when the heel latch is at its forwardmost position for maintaining the heel latch out of engagement with the heel of the boot when the heel latch is at its rearwardmost position.
  • the latch engagement and disengagement means has an operating lever pivotally mounted on the frame rearwardly of the rotatable heel latch for rotating or permitting rotation of the heel latch to its forwardmost position, and it also has a spring load piston mounted for longitudinal movement on the frame rearwardly of the heel latch for rotating the heel latch to its rearwardmost position.
  • the operating lever is rotatable from a generally horizontal position to an angled with respect to horizontal position and return.
  • the operating lever is directly connected to the heel latch by means of a connecting link so that rotation of the operating lever to its horizontal position rotates the heel latch to its forwardmost position and maintains the heel latch in this position and so that rotation of the operating lever to its angled position rotates the heel latch to its rearwardmost position at which position it is maintained by the spring loaded piston.

  • touring skis are long, narrow and of very light construction usually either of laminated wood or fiber glass.
  • Touring ski boots are light weight and low cut with a very flexible sole to allow the boot heel to be raised freely while walking or gliding on the skis.
  • Touring ski bindings normally attach only the toe of the ski boot to the ski to allow for walking and gliding movements on the part of the skier.
  • the skis and ski boots shown in the drawings are of the touring type. Specifically, as shown best in FIGS. 1 to 3 the touring ski boot 11 is secured to the touring ski boot 12 by a conventional touring ski toe binding (not shown) of the type well known in the art. The heel of the ski boot 11 is releasably secured to the ski 12 by the ski boot heel binding 14 of the invention.
  • the heel binding comprises a frame 15 secured to the ski 12 by the screws 16.
  • a rotatable heel latch 17 is pivotally mounted on the frame by means of the transverse pivot pin 18.
  • the heel latch is rotatable forwardly to its forwardmost position at which position it is adapted to engage the heel of the touring ski boot 11 as shown best in FIGS. 1 and 5, and it is rotatable rearwardly to its rearwardmost position at which position it is out of engagement with the heel of the ski boot as shown best in FIGS. 2 and 6.
  • Heel latch engagement and disengagement means are provided for maintaining the heel latch 17 in engagement with the heel of the ski boot when the heel latch is at its forwardmost position and for maintaining the heel latch 17 out of engagement with the heel of the ski boot when the heel latch is at its rearwardmost position.
  • the heel 19 of the ski boot 11 is advantageously provided with a heel latch lug 20 which extends rearwardly of the heel in position to be engaged by the heel latch 17 when the heel latch is at its forwardmost position.
  • the latch engagement and disengagement means comprises an operating lever 21 pivotally mounted on the frame 15 by means of the transverse pivot pin 22 located rearwardly with respect to the heel latch 17, the operating lever being rotatable to a generally horizontal heel latch locking position as shown in FIG. 1 and to an angled with respect to horizontal heel latch disengagement position as shown in FIGS. 2 and 3.
  • a connecting link 23 is pivotally connected at its forward end to the heel latch 17 above the axis of rotation (that is, above the pivot pin 18) of the heel latch, and the connecting link 23 is pivotally connected at its rearward end to the operating lever 21 forwardly of the axis of rotation (that is, forwardly of the pivot pin 22) of the operating lever.
  • a spring loaded piston 25 is mounted for longitudinal movement on the frame 15 rearwardly with respect to the heel latch 17, the piston 25 pivotally engaging the heel latch 17 at a pivot point 27 that is below the axis of rotation of the heel latch.
  • the heel latch 17 When the operating lever 21 is rotated to its horizontal position as shown in FIGS. 1, 4 and 5, the heel latch 17 is rotated to its forwardmost boot heel engagement position as also shown in FIGS. 1, 4 and 5.
  • the connecting link 23 is advantageously pivotally connected to the operating lever 21 at a point on the operating lever that is disposed below the axis of rotation of the operating lever when the operating lever is at its horizontal position.
  • the heel latch 17 is firmly held or “locked” at its boot heel engagement position by the connecting link 23 and operating lever 21, upward pressure of the heel latch lug 20 against the heel latch 17 being resisted by the heel latch which is unable to rotate rearwardly when the operating lever is at its horizontal position.
  • the operating lever 21 When the operating lever 21 is rotated to its angled position as shown in FIGS.
  • the heel latch 17 is rotated to its rearwardmost boot heel disengagement position as also shown in FIGS. 2, 3 and 6.
  • the spring loaded piston 25 urges the heel latch 17 toward its rearwardmost position, and the piston 25 tends to maintain the heel latch at this position.
  • the heel latch 17 When the heel latch 17 is at its boot heel engagement position as shown in FIGS. 1, 4 and 5, the heel 19 of the ski boot 11 is firmly held against the ski 12, thereby permitting firm control of the ski when skiing downhill.
  • the heel latch 17 When the heel latch 17 is at its boot heel disengagement position as shown in FIGS. 2, 3 and 6, the heel of the ski boot is free to lift from the surface of the ski thereby facilitating walking and gliding on relatively level surfaces.
  • the heel latch 17 can readily be moved from its boot heel engagement position to its boot heel disengagement position by pressing on the rearward end of the operating lever 21 with a ski pole 29 as shown in FIG. 2, and it can readily be returned to its ski boot engagement position by pressing on the forward end of operating lever with the ski pole.
  • the binding 14 comprises a frame 30 secured to the ski 12 by the screws 31.
  • a rotatable heel latch 32 is pivotally mounted on the frame 30 by means of the transverse pivot pin 33.
  • the heel latch 32 is rotatable forwardly to its boot heel engagement position as shown in FIGS. 7 and 9 and is rotatable rearwardly to its boot heel disengagement position as shown in FIG. 10.
  • the heel latch engagementt and disengagement means includes an operating lever 34 that is pivotally secured to the frame 30 by means of the transverse pivot pin 35 located rearwardly with respect to the heel latch 32, the operating lever 34 being rotatable from a generally horizontal position as shown in FIG. 7 to an angled with respect to horizontal position as shown in outline in FIG. 9.
  • a spring loaded piston 36 is mounted for longitudinal movement on the frame 30 rearwardly of the heel latch 32, the longitudinal axis of the piston 36 being generally perpendicular to the axis of rotation (the pivot pin 33) of the heel latch 32.
  • a connecting rod 37 is pivotally connected at its rearward end to the piston 36 and is pivotally connected at its forward end to the heel latch 32 at a pivot point 39 thereon eccentric with respect to the axis of rotation of the heel latch.
  • the spring 40 of the spring loaded piston 36 presses the piston and the connecting rod 37 firmly against the heel latch 32 so that when the eccentric pivot point 39 is positioned above the pivot pin 33 a shown in FIG. 9 the heel latch 32 is releasably held at its forwardmost boot heel engagement position by the spring loaded piston 35 as also shown in FIG. 9, and when the eccentric pivot point 39 is positioned below the pivot pin 33 as shown in FIG. 10 the heel latch 32 is releasably held at its rearwardmost boot heel disengagement position by the spring loaded piston 36 as also shown in FIG. 10.
  • the spring 40 is a flat or leaf spring the center of which presses against the rearward end of the piston 36 and the ends of which are pressed by the forwardly extending ends of the spring compressor member 41.
  • the spring compressor member 41 is mounted for longitudinal movement in the recess 42 formed in the frame 30, and in the embodiment shown it comprises a C-shaped member the forwardly extending ends of which press against the ends of the spring 40 as previously noted.
  • the pressure of the spring 40 against the piston 36 may be adjusted by means of the adjustment screw 43 which, when rotated, moves the spring compressor member 41 either forwardly or rearwardly as desired.
  • Other types of springs such, for example, as a compression coil spring may be used in place of the leaf spring shown in FIG. 8.
  • a spring means 45 mounted on the frame 30 urges the operating lever 34 to its horizontal position.
  • the heel latch 32 When the heel latch 32 is at its forwardmost boot engagement position as shown in FIGS. 7 and 9, the heel latch 32 is maintained at this position by the spring loaded plunger 36 and can only be rotated to its rearwardmost boot heel disengagement position by overcoming the pressure exerted by the spring 40 against the piston 36. This can be accomplished by manually pressing the heel latch 32 rearwardly by hand or by means of a ski pole. In addition, the heel latch 32 can be rotated rearwardly by upward pressure exerted thereon by the heel latch lug 20 on the heel of a ski boot. This upward pressure can either be applied deliberately by the skier when he wishes to release the heel of his ski boot or it can be applied automatically by the heel latch lug 20 in the event of an accidental fall by the skier. In the latter case the automatic rearward rotation of the heel latch 32 serves as a safety release feature in the event of an accidental fall. As noted, the force required to overcome the pressure of the spring 40 may be increased or decreased by appropriate adjustment of the spring compressor member 41 and adjustment screw 43.
  • the heel latch 32 When the heel latch 32 is at its rearwardmost boot heel disengagement position as shown in FIG. 10, the rearward surface of the heel latch rests against the forward facing surface of the operating lever 34, and the heel latch 32 is releasably held at this position by the spring loaded piston 36. When at this position the heel of the ski boot may be freely lifted from the surface of the ski as required when walking or gliding on the ski. The heel latch 32 is returned to its forwardmost boot heel engagement position by pressing down on the rearward end of the operating lever 34. This causes the forward end of the operating lever 34 to rise and thereby press or cam the heel latch 32 to its forward position as indicated in FIG. 9 of the drawings.
